The invention provides a worm gear oil composition and a preparation method of the worm gear oil composition. The worm gear oil composition comprises a combination of polyether oil base oil, a 2, 2, 4-trialkyl-1, 2-dihydroquinolines antioxidant and a metal passivator. The worm gear oil composition provided by the invention has outstanding oxidation stability, high-temperature detergency, extreme pressure antiwear property, viscosity-temperature performance, anti-foaming performance and high comprehensive performance; and in addition, the preparation method is simple and wide in applicable scope.
Description
Technical field
The present invention relates to a kind of combination of oil for pair of gear worm, more definite is peace and quiet type combination of oil for pair of gear worm of a kind of long lifetime.
Background technology
Transmission mechanism is one of gear-driven type, in order to transmit power and the motion between the staggered diaxon in space.The worm and gear transmission has that volume is little, transmission speed ratio is big, running steadily, little, the big characteristics of worm gear output torque of noise, thereby obtained widespread use.Transmission has very important influence to worm and gear lubricating oil to worm and gear, and it can reduce to rub, reduce wear, reduce temperature rise, improve worm gear pair transmission efficiency and work-ing life.
Worm drive is because the slip between the flank of tooth is relative longer than geartransmission duration of contact big and tooth, so the frictional wear situation is outstanding, and the general requirement oil viscosity is bigger, and higher viscosity index is arranged, and oiliness will be got well, and contains some special additive.Worm couple is many in addition is complementary with bronze, brass worm wheel and steel worm and gear, and copper is very sensitive to sulphur, therefore should not adopt the high sulfur-containing extreme-pressure additive of chemically reactive, and the oiliness improver of employing medium activity, to avoid flank of tooth generation chemical corrosion and spot corrosion, this also is the maximum differential of worm and worm wheel oil and other gear oils.
Along with equipment develops to the high-speed overload direction, present worm and gear oil product can not satisfy the demand of development, shows as mainly that oil product wears no resistance, resistance to emulsion is poor, oxidation stability difference etc.Present oil product is base oil with mineral oil mostly, adds pour point depressant, viscosity index improver, sulfur-bearing and/or phosphorous extreme pressure anti-wear additives, phenol type or additive combinations such as amine type oxidation inhibitor, metal passivator, oiliness improver and emulsion splitter and forms.Mineral oil easily produces greasy filth except oxidation, outside the contamination and plugging equipment, the characteristics that also have oiliness, as the combination of oil for pair of gear worm of mentioning among the Chinese patent application CN1727458A, wherein add two kinds of total amounts altogether and reached 1.4% oiliness improver reaching corresponding oiliness, this makes the resistance to emulsion variation (greater than 20min) of said composition, because oiliness improver is tensio-active agent, add-on too much can influence the oil product demulsification resistance.Oxidation stability is to influence the worm and worm wheel oil important factor in work-ing life, but people are still not enough to the concern of its oxidation-resistance at present, Chinese patent application CN102051252A discloses a kind of energy-saving worm and gear gear oil prescription, only contain oiliness improver, extreme pressure anti-wear additives, anticorrosive agent etc., do not add antioxidant.
